# The collector can be built either as dynamic or as static library.
# Select the library type you need.
#MAKE_AS_DLL=1
MAKE_AS_LIB=1

# Select calling conventions.
# Possible choices are r and s.
CALLING=s

# Select target CPU.
# Possible choices are 3, 4, 5, and 6.
# The last choice available only since version 11.0.
CPU=5

# Set optimization options.
# Watcom before 11.0 does not support option "-oh".
